A random-effects meta-analysis was conducted to investigate the effect of mycotoxins (MT) without or with the inclusion of yeast cell wall extract (YCWE, Mycosorb, Alltech, Inc., Nicholasville, KY, USA) on laying hen performance. A total of 25 trials were collected from a literature search, and data were extracted from 8 of these that met inclusion criteria, for a total of 12 treatments and 1774 birds. Laying hens fed MT had lower ( < 0.05) body weight (BW) by -50 g, egg production by -6.3 percentage points, and egg weight by -1.95 g than control fed hens (CTRL). Inclusion of YCWE during the mycotoxin challenges (YCWE + MT) resulted in numerically greater ( = 0.441) BW by 12.5 g, while egg production and egg weight were significantly ( < 0.0001) higher by 4.2 percentage points and 1.37 g, respectively. Furthermore, economic assessment calculations indicated that YCWE may not only support hen performance but also resulted in a positive return on investment. In conclusion, mycotoxins can play a role in negatively impacting laying hen performance and profitability. Inclusion of YCWE in feed with mycotoxin challenges provided benefits to egg production and egg weight and may support profitability. As such, the inclusion of YCWE could play an important role in minimizing mycotoxin effects and in turn aid farm efficiency and profitability.
采用随机效应荟萃分析研究了在不添加或添加酵母细胞壁提取物（YCWE，Mycosorb，Alltech，Inc.，Nicholasville，KY，USA）的情况下霉菌毒素（MT）对蛋鸡生产性能的影响。通过文献检索共收集了 25 项试验，其中 8 项符合纳入标准的数据被提取出来，共有 12 种处理方法和 1774 只鸡。与对照组（CTRL）相比，饲喂 MT 的母鸡体重（BW）降低（<0.05）了-50g，产蛋率降低了-6.3 个百分点，蛋重降低了-1.95g。在霉菌毒素挑战期间添加 YCWE（YCWE+MT），BW 增加了 12.5g（=0.441），产蛋率和蛋重也显著（<0.0001）增加了 4.2 个百分点和 1.37g。此外，经济评估计算表明，YCWE 不仅可以支持母鸡的生产性能，而且还可以带来积极的投资回报。总之，霉菌毒素可能会对蛋鸡的生产性能和盈利能力产生负面影响。在饲料中添加 YCWE 应对霉菌毒素的挑战可以提高产蛋率和蛋重，并可能支持盈利能力。因此，添加 YCWE 可以在最大程度上减少霉菌毒素的影响，从而提高农场的效率和盈利能力。
